After expressing disappointment that Guess was still working with designer Paul Marciano on social media last month, Kate Upton is coming forward with allegations against the brand's cofounder and chief creative officer, sharing her own #MeToo story.

In an interview with Time, the 25-year-old model recalled an encounter with Marciano on the set of a Guess Lingerie campaign back in 2010, when she was 18. She alleges that the designer "forcibly grabbed my breasts and started feeling them" upon their first encounter, and "continued to touch me in a very dominating and aggressive way, grabbing my thighs, my arms to pull me closer, my shoulders to pull me closer, my neck, my breasts, and smelling me." According to Upton, this all happened in front of the photographer, Yu Tsai—and though she said he tried to step in at the model's request, Marciano reportedly kept on with the "constant grabbing."

"At one point he forcibly grabbed the back of my head so that I could not move and started kissing my face and my neck," Upton told Time. "I remember not wanting to say, 'Get off of me' because I didn’t want to open my mouth to say anything because I didn’t want him to be able to put his tongue in my mouth. I had two options: do everything I could to wiggle away and avoid his pursuit, or punch the CEO of Guess. So I decided to just wiggle away."

Upton booked another job with Guess a month later—and on this occasion, she says, Marciano "started calling me asking to come up and see how my room is." Even after she declined, she explained to Time that "he continued to insist…. After several denials, I just turned off my phone and locked the door and tried to get some sleep. I was terrified. All I could think was if he was able to get into my room it would not be good." The following day Upton was told she had been fired: "Someone had called my agency to say I had gotten fat and would not be needed on set [that day]. I was devastated, especially because at this point no one from Guess had even seen me."

This behavior would continue, according to the model, through May 2011, when Upton would stop working with Guess as regularly. She said she would receive messages from Marciano directly, which, by her accounts, ranged from him "telling me how excited he was to see me" on set to him "[asking] if I thought of him when I was posing sexy on set." She told Time she felt "that if I cut off communication with him, I wouldn’t be booked again," having seen her collaborators and protectors like Tsai be taken off certain shoots in apparent retaliation. On her last project with Guess, Upton remembered Marciano as being "outwardly rude and degrading the entire time…. I was then told to leave because Paul had said, 'Get that fat pig off my set.'"

Following her success with Sports Illustrated, Upton said she received offers to model from the brand again, but she felt torn over whether she should take the money (which was reportedly in the six figures), but ended up declining when she would start getting text messages from Marciano again.

In a statement to Time, Marciano denied Upton's accusations, saying he has "never been alone with Kate Upton. I have never touched her inappropriately. Nor would I ever refer to a Guess model in such a derogatory manner." He added that he's a supporter of the #MeToo movement, but "will not allow others to defame me and tarnish my reputation. I have pledged to Guess and its board of directors my full support and cooperation with a fair and impartial investigation." Glamour has reached out to Guess for comment, and will update this story when we hear back.

"Paul used his power to make me feel insecure and powerless, but I’m not going to let him intimidate me anymore," Upton said. "These men think they are untouchable, but times are changing."

According to Upton, part of the problem lies in the lack of protections on set for models. "You have no idea who to tell [about abuse]. And you’re constantly told about the models who are OK with this behavior and how successful they are." It goes back to what she described to Time as a "culture of complacency and tolerance," where this type of treatment is not only tolerated but survivors are "incentivized" to stay quiet so as to keep booking jobs and getting paid.

"Nobody has a right over my body just because they view me as sexy or a sex icon," Upton said. "I think people need to be educated on the definition of consent. I don’t think there are any blurred lines in this. I don’t think you should be touching people at the workplace, and I don’t think you should be sexually speaking to a model as they’re doing their profession."
